Androgenic side effects, although much lesser than Testosterone, are still a possibility with Equipoise. Although Equipoise interacts with the 5AR (5-alpha reductase) enzyme, which is the enzyme responsible for the conversion of Testosterone into the stronger androgen DHT (Dihydrotestosterone), it does not convert into DHT but instead converts into Dihydroboldenone (DHB). Although it converts into DHB, studies have found Equipoise to undergo this conversion at a much lower rate than the conversion of Testosterone into DHT. Androgenic side effects can include: increased oily skin (sebum secretion), increased acne formation (linked to sebum secretion), bodily and facial hair growth, and the increased risk of experiencing male pattern baldness (MPB) if the individual possesses the genetic predisposition for it.

At a K-1 WGP event in Las Vegas on August 17, 2007 two fighters, Rickard Nordstrand and Zabit Samedov , both tested positive for boldenone.  Alexandre Franca Nogueira tested positive for boldenone in July 2008.
